MicroRNA Discovery Reveals How Early Lung Lesions Dodge the Immune System
Researchers identify miR-149-5p as a key driver of immune escape in bronchial lesions that can progress to squamous cell lung cancer.
Key Takeaways
- Boston University identifies miR-149-5p as a microRNA that suppresses immune recognition in premalignant lung lesions
- The microRNA silences NLRC5, a master regulator of antigen presentation, allowing abnormal cells to hide from immune surveillance
- Analysis of 167 bronchial biopsies showed a consistent inverse relationship between miR-149-5p and NLRC5 in progressive lesions
